Abstract: 

AIMS: The aim of the study was to assess whether the oral intake of cranberry juice cocktail compared with apple juice was associated with a significant difference in urinary symptoms experienced during radical external beam radiation therapy (EBRT) for prostate carcinoma.

MATERIALS AND METHODS: One hundred and twelve men with prostate cancer were randomised to either 354 ml cranberry juice or apple juice a day. Stratification was based on a history of a previous transurethral resection of prostate (TURP yes/no) and baseline International Prostate Symptom Score (IPSS or = 6) of urinary symptoms.

RESULTS: The maximum IPSS (MRT) and the maximum change in IPSS from baseline (DRT) are used to report the results. We analysed the effects of juice allocation on DRT and MRT using analysis of covariates (ANCOVA). We observed no significant difference for DRT (P = 0.39) or MRT (P = 0.76) related to the consumption of cranberry compared with apple juice. However, we found a significant relationship between the history of a previous TURP and both DRT (P = 0.01) and MRT (P = 0.01). The history of a previous TURP was associated with lower values for both end points. Baseline IPSS was significant for DRT (P = 0.004) and MRT (P or = 6 cut point on MRT (P

CONCLUSIONS: This study shows no significant difference in the urinary symptoms experienced during EBRT related to the consumption of cranberry juice compared with apple juice.
